JOSEPH B. STRAUSS, OFCHIKLAI'JrO,113111351015.` i j ELEVATED RAILWAY.

Be it known that I, JosnrH B. Srinioss, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented a certain new and useful Improvement in Elevated Railways, of wliichthe following is a specification.

This invention relates to elevated structures, and has for its object to provide a new and improved structure of this construction 'particularly' adapted for elevated railways,`

and which can be made and installed at a rmuch lower cost than the structures now in use, and which will at the same time be strong, durable Aand eflicient.

Referring now to the accompanying drawings-,-

Fig. 1 is a side elevation of one form of structure embodying the invention;

' Fig. 2 is aI plan view of the device shown vin Fig. 1;

Fig..3 is an enlarged sectional view taken -on line 3-3 of Fig. 1;

Fig. 4 is an enlargedview through one of the girders showing a car in position; 'i Fig. 5 is an enlarged sectional view taken on line 5-5 of Fig. 4, with the truck and car omitted;

" Fig. 6 `is a. sectional view taken on linev 6-6 of 'Fig 4 with the motor and vcar omitted r,en eor Fig. e'

Fig. 7 is an enlarged sectional view show ing the rail support and connection;

Fig. 8 is la sectional view taken on line Fig. 9 is a sectional view taken on line 9 9 of Fig. 3; Like numerals refer to like'parts throughout the several figures.

Referring now to the accompanying drawe ings, I have shown one form of elevated ystructure embodying the invention and particularly adapted for elevated railways. ln' this construction there is provided a series of centralposts 1. These posts are made up of skeleton metal upright members 2 and cross members 3, which are connected together of forni a skeleton post. These zposts are thenfastened to suitable bases. :These bases may be arranged in any desired manner. prefer to use for each base the separated piers or supports 4, which preferably incline from the bottom to the top,

and which provide a space 5 between them wherein sewers and conduits forv electric wires and gas pipes, etc. lmay be located.

Specification of Letters-Patent. 4 Patented Aug. 15` 1922.` Application filed November 4, 1921. -Seria1r1,\1'o. 512,721. v i 'i v vRods or bolts 8 are connectedfwithvthefGlQSs niece.

The V posts are provided with enlarged lower ends 9, which; havev engaging partsy 'for the bolts 8, and `by means ofl which the posts are removably attached to the cross pieces ofthe base. By means of this construction the bases may be .rst made up and then the skeleton posts 'attached thereto.v

These skeleton ,posts arel Lprovided with enlarged ,heads 10, and after the metal skeleton posts are placed in position they maybe filled with concrete 102'* so ,asv to form'reinforced concrete posts. y

Mounted upon these central posts arethe separated concrete girders 11. These Yare made up of skeleton metal members 13,13" 14. i The skeleton metal members may 'be `first erected, and then filled with concrete so as to form reinforced concrete girders.

These girders `have open spaces 'between them, and they are connected at intervals by vertical concrete diaphragms 15 and horizontal ,diaphragms 16 (see Fig. 5), the diaphragms `preferably lbeing unitary. with the V,concrete girders and also preferablyv located at theends .of the girders.` Connected with thegrders 11, and `projecting therefrom at intervals are cantilever brackets 17. `These .cantilever ,brackets are preferably located opposite" the lvertical diaphragms 15, and the brackets on oneside are connected across transmitting the load of each track carried by the cantilever arm, tothe girder ,adja-v ycent thereto and also to the other girder.

The brackets 17 have the .cantilever memv'bers 2O and 21, upon which'arecarried the rails-22 ofthe track. The ends` of these 'cantilever members]v are opposed to ,each fother, but are. separated by a space, fand theregare guard rrails `23near the lends, yof 4 c Above the rails `22 ,is aY these members. space or passage 24. Mountedonthe rails 22 so as to run along in the space 24, aretrucks 25, upon which I,are suspended the cars v26. y'These trucks arepoperated'by any suitable motor,` such ast'he electric motor to the opposite girder by the metal connect- Ving pieces 18. 'Means rare thus providedv for i ythen later placed in position.

extend along beneath vthel two cantilever members, and in addition to strengthening the structure, yact as'guides for the cars. It will be noted that the rollers or engaging parts 30 which engage 'these guides are at the top of the car.

`Referring now to the rails 22 and associated parts it will be noted that the members or sleepers 20 have on opposite sides thereof, the angles 32, and that the bolts 33 pass through these sleepers and these angles and the guide rail 23 and the plate 34 (see Fig. 7

.lt will be seen that with this construction the skeleton steel work ot the posts and of the girders may be erected, and the concrete By means of this construction the cost per mile of an A elevated structure is very greatly reduced,

and at the same time a durable, strong, safe and etlicient elevated structure is produced.

l have set forth' in detail a particular construction embodying the invention but it is of course evident that the parts may be varied in many particulars, without departmg from the spirit of the invention as set 'orth'in the claims hereto appended, and l thereforevdo not limit myselr' to the particular construction shown.
